Grasshopper generating RhinoDotNetCrash.txt at desktop when closing a file

Hi all,

Every time I close a GH file, it creates a RhinoDotNetCrash.txt on my desktop. I already tried to uninstall and go back to the SR version without luck. I suspect it started either after installation of the latest Rhino SRC or Windows update as I did them both around the same time.

Looks like it is caused by the Bifocals plug-in because as soon as I “uninstall” (read delete) the file, I no longer get the RhinoDotNetCrash.txt file.

Please see info below:

Any input on how to overcome this small issue is much appreciated.

Remove Bifocals then.

It seems Bifocals mishandles when there’s no active document.

You can’t do anything, apart from uninstalling Bifocals. The Bifocals developer can fix the issue, and I can put extra error handling around the event which is ultimately causing Bifocals to throw the exception. (I’ve just done that, the next Rhino7 release will have this additional protection).

@Keyu and David: Thanks a lot for the feedback and info provided, much appreciated. It brings me a certain relief to know that the “culprit” is not at Rhino´s end as I was worried that I had messed up my installation after the SRC and Windows Updates.

Cheers!

Rick.
